Wireless standards

Question 1

What GHZ range does 802.11a operate in? And what speed does it throughput? Does it use MIMO, or MU-MIMO?

Answer 1

5ghz

54 mbit per second

Question 2

What does the 802.11b frequency range operate in? And what speed does it throughput? Does it use MIMO, or MU-MIMO?

Answer 2

2.4 ghz
11 mbit per second

Longer range but slower speed
Lower frequencies mean less absorption.

Question 3

What frequency does 802.11g operate in and at what speed does it throughput? Does it use MIMO, or MU-MIMO?

Answer 3

2.4ghz
54 mbit per second

Question 4

What frequencies does 802.11n operate in? what Wi-Fi standard is this called, what speed does it throughput and what mhz does it allow per channel? Does it use MIMO, or MU-MIMO?

Answer 4

Wi-Fi 4
5ghz and 2.4ghz
40 mhz per channel up to 4 channels
600 mbits per second

This standard also uses MIMO

Question 5

What frequencies does 802.11ac operate in, what’s its WI-FI name? What MHz speeds does it allow?
What’s it’s total throughput? Does it use MIMO, or MU-MIMO?

Answer 5

Wi-Fi 5
5ghz ONLY
160 Mhz channel bandwidth (up to 8 channels)
6.9 gbits per second throughput

This introduced MU-MIMO

Question 6

What frequencies does 802.11ax operate in? What’s it’s Wi-Fi name? What’s it’s MHz channel width? And it’s total throughput? Does it use MIMO, or MU-MIMO?

Answer 6

Wi-Fi 6
5 ghz or 2.4
20,40,80,160 MHz channel widths
1.2 gbps per stream
9.6 gbs max throughput
8 bi directional MU-MIMO streams
OFDMA
